Hey! You just got a new MacBook Pro with Retina display and you want to read your favorite books with the Kindle app, right? Well, you might notice that if you downloaded the Kindle app from the Apple app store, the text is blurry. BUMMER! Don’t despair! Try this fix before you cry. Delete your Kindle app that you downloaded from the App store, and deregister your Kindle for that device. Then go to the Amazon store and get the Kindle app there. Here is a LINK as of 4/6/14. Install this app instead of the other one. It might say you are attempting to over-write a newer file. That is fine. This app from the amazon store is the one you want! It should fix your blurry situation. Be sure to register this app so you can get all of your books. I hope this helps! :)
